» Biocompatibility of dental materials used in contemporary endodontic therapy: a review. Part 1. Intracanal drugs and substances

Irrigation solutions and intracanal medicaments are used within the root canal to clean and aid in disinfecting the dentinal walls. Although these materials are intended to be contained within the root canal, they invariably contact the periapical tissues, either through inadvertent extrusion through the apex or leaching. This paper is a review on the methodology involved in biocompatibility testing followed by a discussion on biocompatibility of contemporary intracanal drugs and substances used in endodontics.
» Histological evaluation of teeth with hyperplastic pulpitis caused by trauma or caries: case reports

Aim.
The purpose of this histological study was to examine teeth with hyperplastic pulpitis caused by trauma or caries.

Key learning points.
  • Hyperplastic pulpitis is a type of irreversible chronic open pulpitis.
  • Young permanent teeth with hyperplastic pulpitis caused by trauma or caries have a great inherent defensive capacity to heal.
» A preliminary analysis of the morphology of lateral canals after root canal filling using a tooth-clearing technique

Aim.
This study used a modified tooth-clearing technique to allow observation of accessory canals following filling with a warm gutta-percha technique and one of two endodontic cements.

Conclusions.
The modified tooth-clearing technique allowed observation of fine morphological details in all specimens. Effective gutta-percha filling was evident in most of the wide coronal lateral canals whilst the apical narrow ramifications were often incompletely filled by cement. Overall AH-Plus demonstrated better diffusion into lateral accessory canals compared to Pulp Canal Sealer.
» Short-term periradicular tissue response to mineral trioxide aggregate (MTA) as root-end filling material

Aim.
The aim of the present study was to evaluate the short-term response of periradicular tissues to MTA when used as a root-end filling material in ideal tissue conditions.

Conclusions.
MTA is a biocompatible material that stimulates periradicular tissue repair at the root-end situation; however, the nature of the newly formed tissues requires further elucidation.
» Comparison of procedural errors resulting during root canal preparations completed by junior dental students in patients using an ‘8-step method’ versus ‘serial step-back technique’

Aim.
To compare procedural errors occurring during preparation of root canals by junior dental students in patients using a new ‘8-step method’ versus traditional ‘serial step-back technique’.

Conclusions.
The new ‘8-step method’ resulted in fewer procedural errors than the traditional ‘serial step-back technique’ when junior students prepared root canals in patients.
